At what cost

For less than 60 dollars, Geniani 4L Cool Mist Smart Aroma is definitely not the cheapest ultrasonic humidifier out there. You do get 1-year extra warranty, smart mode, and night light bundled in together. If you don't need all the extra features, you can probably get a basic humidifier for less than 30 bucks. Nonetheless, the auto humidification features itself is worthy of the little price bump.
The best place to get Geniani Smart Aroma Ultrasonic Humidifier is of course Amazon. It comes with a good discount, bundled deal, with both black and white color options available. The official Geniani website is also doable as it comes with free shipping regardless of the order amount. Last by not least, you can try your luck at retailers like Best Buy, Walmart, Home Depot, or Costco. In any case, you will still be protected by 30 days return policy if you have a change of thought.
